Background Currently, digital filters are employed in a wide range of signal processing applications, using fixed- and floating-point processors. Regarding the former, some filter implementations may be highly prone to errors, due to problems related to finite word-length. In particular, signal processing modules may produce overflows and unwanted noise, which are caused by quantization and round-off...
This paper presents an Investigation regarding the performance of video and image encoders, when applied to the compression of surface electromyographic signals. In addition, a new preprocessing technique is introduced, called euclidean distance sorting (EDS), which has the potential to increase the exploitation of intersegment correlations. The experiments were carried out with real isometric records,...
This paper presents an effective system for dynamic integration of appliances into a ZigBee home network through home gateways based on Web services. The proposed architecture will be described along the paper. The resulting system has been implemented and was used in experiments in a home network test bed in order to prove its feasibility and effectiveness. The obtained results are promising. This...
